Question normal

The participants’ estimate of the level of nicotine of the assigned study cigarettes was significantly lower in those smoking cigarettes with 2.4 mg of nicotine or less per gram than those smoking cigarettes with 15.8 mg of nicotine per gram. I am wondering if this 'incomplete blinding' affect the results in any way.

Or doesn't it really matter because this difference in the participants' estimate of the level of nicotine between in the reduced-nicotine group and in the standard-nicotine group is indeed the study's intended subjective effect? Please correct me if I'm wrong for labeling it 'incomplete blinding.'
